Last month, Florida ’s Brevard County school board passed a new dress code policy to prohibit students from dressing like animals. Citing student complaints about “furries,” the board forbade attire emulating “on-human characteristics,” e.g., cat ears and dog collars.

Some say that Brevard’s new dress code violates President Joe Biden ’s proposed Title IX regulations.

The public controversy over the proposed regulations centered on the redefinition of “sex” to mean “gender identity.” But what exactly does “gender identity” mean? The regulations do not provide a definition.
